How often do you take breaks while working?

Question

General advice that I have recieved says you should take breaks every 30 mins, especially if the work involves being seated at one place. This also works well with the Promodoro technique. But 30 mins would definitely not cut it for tasks that need prolonged focus. I have also noticed people suggesting taking breaks 90 mins. I wonder what's the optimum frequency of breaks.

A better question would be how often do I tear myself away from the opiates of the internet? In a fictional character's immortal words, "I'd say in a given week I probably only do about fifteen minutes of real, actual, work." (Office Space, 1999)
